Low noise amplifier (LNA) with distortion and noise cancellation

A low noise amplifying system comprising:

• a first signal path comprising an amplifying path;
• and
• a second signal path comprising a cancellation path configured to cancel noise and distortion independently,
• wherein devices in the amplifying path are configured to create distortion having a first value and a first sign, and devices in the second signal path are configured to create distortion having approximately the first value and a second sign opposite the first sign, and
• wherein the first signal path and the second signal path are inductor-less.

A mobile communication device comprising:

• a transceiver comprising a power amplifier module comprising:
• a first path coupling an input node and an output node, the first path comprising a low noise amplifier (LNA);
• and
• a second path coupling the input node and the output node, the second path electrically parallel to the first path, the second path comprising cancellation circuitry comprising:
• a noise cancellation circuit comprising a noise canceling amplifier configured to adjust an impedance at the input node;
• and
• a distortion cancellation circuit, such that the PA module is inductor-less.
